Binder is a tablet app (iPad and some Android devices) that allows you to pull PowerPoints, PDFs, and Word documents from D2L, Dropbox (www.dropbox.com), Skydrive, or photos, then view and annotate them via the Binder app. The Binder app contains two main areas: My Binder and Fetch. Use the Fetch feature to access documents, then view them via My Binder.
